Climate bulletin - June 2013

Summary of the world's climate in June 2013.

The global average temperature in June 2013 was 0.45 ± 0.15 °C above the 1961-1990 average. Sea-surface temperatures in the tropical Pacific cooled slightly but remained above La Niña thresholds. Together with other atmospheric indicators, this is consistent with ongoing neutral El Niño Southern Oscillation conditions.

In June, most land areas were warmer than average. Limited areas of the north east United states, Europe, central Russia, India, Australia and western parts of South America were colder than average. Over Eurasia, the temperature pattern was similar to that in May. Cooler than average conditions over western Europe and an area of Central Russia were separated by an area where temperatures were much warmer than average.

Globally, sea-surface temperatures were above the long-term average, but slightly cooler than in May. Sea-surface temperatures in the eastern tropical Pacific were cooler than average with cooler-than-average or near-average areas scattered across the Pacific. In contrast large areas of the south and north Pacific were a degree or more warmer than average. In the north Atlantic, continued cold weather over the UK and western Europe from early in the year meant that sea-surface temperatures off western Europe were colder than average. However, above average air temperatures further east are associated with above average sea-surface temperatures in the eastern Mediterranean. The far north Atlantic and an area to the east of Newfoundland were also warmer than average.
